Our first morning in San Francisco included a city tour. The temperatures here dropped by 20 degrees compared to the desert and we had rolling fog first thing in the morning which clouded the views from Twin Peaks. We ended up in Sausalito - a really nice artsy place with lots of galleries and left the tour bus here and went back to San Francisco by Ferry. My new camera's panoramic feature captured the 'Frisco skyline perfectly!
The cable cars are turned round on a table at the end of the line each end. Fascinating to watch. If you want to be guaranteed a seat, you need to queue here and the queues are horrendously long whatever time of day.
